Windows 11 24H2 Build 26100.2605 LTSC 2024 English x64 Ultimum OS

(x64) | Languages: English | File Size: 5.1 GB

This build, based on Windows 11 LTSC, prioritizes broad compatibility with various desktops, laptops, and peripherals, while delivering the performance expected from a lightweight Windows 11 installation. Instead of removing components, this build disables certain services (detailed in the specifications below). This approach allows users to easily re-enable any functionality they might require.

Performance gains?
- No UAC. Every time you perform an administrative task on a standard account,
UAC requires you to confirm the action. This adds a tiny bit of overhead. The built-in Administrator account bypasses this entirely.
That also comes with an inherit risk and you must ALWAYS be more vigilant with what you download
With great power comes great responsibility!!

- Elevated Privileges
This account inherently runs with the highest privileges, potentially reducing the need for certain privilege checks and operations that the system performs in the background.

- Driver and Software Compatibility
In some rare cases, certain drivers or older software might have compatibility issues with UAC or standard user accounts. Running them under the built-in Administrator account might resolve these issues, leading to smoother performance.

- The above of course varies from system to system, based mainly on the CPU architecture.
Some CPUs, Mainly AMD, will benefit due to the Cache architecture and size compared to Intel CPUs and so there is no clear indication of how much performance gain there is, but for sure is not making it worse.

- Now the boring part
There have been documented cases, particularly with AMD CPUs and Windows, where kernel address space layout randomization (KASLR) and related security mitigations have led to performance impacts, especially concerning cache performance.

- When some mitigations that use KASLR like Spectre or Meltdown are active we have
Increased Cache Misses
KASLR can lead to increased cache misses,
Kernel Relocation Overhead
The process of relocating the kernel in memory adds a small amount of overhead, which can also contribute to performance loss.

- The normal Admin accounts operate under KASLR but the built-in Local Administrator doesn't.
That makes certain CPUs and architectures run a bit faster and Snapier but only under certain conditions
If the application uses the CPU and RAM intensively the CPU architecture and how it uses Cache and Cache tables.

- Long story short, Some systems may see some noticeable increase in performance some others not so much, but so far I haven't seen anything going slower.

- However, if you are afraid of getting exploited by Spectre or Meltdown (highly unlikely) etc
You can add a Normal admin or even better a normal user account and "experiment" using that.

- Also, that is why we let Defender on, so it will protect the system better.
Use that or any antivirus of your liking.

System Requirements
